Application filed August 19, 1915. Serial No. 46,314.

Z '0 all whom it may concern:

Be it known that I, CHARLES LIBERMAN,

I a citizen of the United States, residing at New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvements in Locks; and I do hereby declare the following to be a full, clear, and exact description of themvention, such as will enable others skilled in the art to whichit appertains to make and use the same. I I

This invention relates to new and useful improvements in looks and the principal object of the invention is to provide a novel means for operating the number of bolts of a lock simultaneously.

Another object of the invention is to provide a lock and a casing for the lock, which may be readily attached to a door with lit tle effort on the part of theperson applying the'same. 1

A still further object of the invention is to provide an efficient and simple lock capable of being readily operated and also being of such a construction as to be easily and cheaply manufactured. I

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a view illustrating my improved lock in place in a door. Fig. 2 is a vertical sectional view through the lock.-

Fig.3 is a vertical sectional view through the lock taken at right angles to the point of Fig.2. Fig. 4 is a sectional view on line 4-4 of Fig. 2. Fig. 5 is av sectional view on line 55 of Fig. 2. Fig. 6 is a view similar to Fig. 2, showing portions of the lock removed to more clearly illustrate the details of construction, and Fig. 7 is a view similar to Fig. 6, showing still further portions of the lock removed.

Referring now to the drawings by characters of reference. the numeral 1 designates the face plate, which forms the base of the lock. This face plate is formed intermediate its ends with the flanges 2, which c0- operate with the flanges 3 in supporting the side walls 4 of the lock in place. These side walls are connected at their extreme terminals by the end wall 5 and it willthus be seen thata chamber is Provided in which the operating means are-confined. Secured near each end of the base plate 1 are the casings 6, in which the cooperating bolts are slidable. V V

Slidable in the casing formed by the side walls 4 and the end wall 5 is the central bolt 7 which is supported onthe U-shaped frame 8, the arms of which are formed with the recesses 9, in which the springs 10 rest. These springs are of the compressed coil type and are designed to engage the end walls of each recess and the wall of the plate 1. The, face 11 of the U-shaped frame 8 is designed to be engaged by the key of the look when the same is operated to throw the bolt into locking position.

Overlying thefU-shaped frame 8 is a suit able U-shaped guard plate 12, the bight por-* tion 13 of which is disposed at the opposite side of the casing hereinbefore referred to.

Slidable laterally within the casing and positioned on top of the plate 13 are the plates 14 tothe ends of which are secured the laterally extendingrods 15, the upper ends of which extend into the casing 6 previously referred to. Pivoted to each rod is a link 17, the opposite end of which is pivoted to the locking bolt 18 in eachofthe casings 6 so that when the rod moves upwardly, the bolt will be-thrown to its.un locked position. In order to normally tend to hold the bolt in locked position there is provided a suitable spring 19 which surrounds eachbolt and abuts a pin. 20, ex-

tending through the bolt and the rear end of 7 each casing 6.

The key used in connection with the lock is best illustrated in Figs. 2 and?) and comprises the shank or stem 21, provided with the head or bit 22. This head or bit is so constructed that when in the locked position illustrated in Fig. 2, the bolt 7 will be forced outwardly and the members 14 will be moved inwardlv, thus allowing the bolts 18 to move outwardly. Upon turning the key to unlock the device,'it will be seen that it will assume the position illustrated by thedotted lines in 2 and the springs 10 within the recesses 9 in the frame 8 will force the bolts inwardly and the bolts 18 will be moved inwardly for the reason that the bit of the key engages the edge of each of the wardly and exerting pressure on the bar 15,

'which will' move the same upwardly and lot members 14 thereby forcing the same upalso be evident that a lock constructed in this manner may be easily and quickly applied to a door as there is very little cutting to do in order to mortise the same.

lrVhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended. claims.

What is claimed is 1-- 1. A look comprising end casings, a central casing, end bolts slidably mounted in said'end casings, springs in said end casings to normally hold said end bolts projected, a central bolt slidably mounted in said central casing, a spring mounted in said central casing to normally hold said central bolt retracted, and means adapted to be oper ated by the turning of a key in one direction to retract said. end bolts and to permit said central bolt to be retracted by its spring, said means being adapted to be operated by the turning of the key in the reverse direction to project said central bolt and to permit said end bolts tov be projected by their springs.

V 2. A lock comprising end casings, a' central casing, bolts slidably mounted insaid end casings, springs in said end casings to normally hold said bolts projected, a frame slidably mounted insaid central casing, a central bolt carried by said frame, a spring in said centralcasing to normally hold said central bolt retracted, said frame being adapted to be operated by the turning of a key in one direction to project said central bolt, the turning of the key in the reverse direction permitting said central bolt to be retracted by its spring, and means adapted 1 to be operated by the'turning of the key in said reverse direction to retract said end bolts, said means permitting said endbolts to be projected by their springs when the key is turned in said first named direction.

3'. A lock comprising end casings, a cen-* tral casing, bolts slidably mounted in said end casings, springs in'said end casings to normally hold said end bolts projected, a frame slidably mounted in said central casing, a central bolt connected to said frame,

verse direction permitting the central bolt to be retracted by itsspring, plates slidably mounted in said central casing and adapted to be operated by the turning of the key in said reverse direction, and aconnection bef tween each plate and each end bolt, said connection retracting said. end bolts when the key is turned in the reverse direction and permitting said end bolts to be pro jected by their springs when the key is turnedin the first named direction.

In testimon whereof I afiix 1n si nature y y a in presence of two witnesses.
